With this Rearmable Differential Switch or automatic reset, it can prevent situations of lack of current and access the following applications: in case of electrical storm or eventual leakage in the electrical network, shots are produced in the differential protection. If in the room where the difference / s is installed there is no one present that detects the absence of current, this trip could cause, among others, the following consequences:
In the domestic field:
- Assaulted housing (the security system would have exhausted the emergency batteries)
- Food in storage in the fridge and freezer could deteriorate due to lack of cold
- Lawn and garden plants and flowers may dry out due to lack of irrigation
- Aquarium fish could die from deficiencies in the oxygenation of water
- Domotica systems would be out of service due to lack of power supply
In the commercial and industrial field:
- Trade, office or ship assaulted (the security system would have exhausted the emergency batteries)
- Perishable goods deposited in cold stores and freezers deteriorate or break the cold chain
- Computers and supervision systems would stop working due to lack of power or they would end up draining the batteries of the UPS
- The refrigeration and air conditioning systems of small server rooms would stop working and could cause serious problems in the computer systems.
- The loss of current and the non-ordered closure of the servers can lead to serious consequences
- The control and inmotica systems out of service due to lack of power supply
With our differentials with automatic reconnection or resettable or self-arming, in case of differential trip, the electric supply is re-established in a short time, avoiding costly losses.
Installing self-arming or resettable differentials, your installation will be safe and efficient saving costly and in many cases irreparable losses through the automatic rearming of the differential.
